如何在android上使用离线捆绑？
我没有在android上看到关于使用offline bundle的文档.
我试图取消注释build.gradle中的代码.

project.ext.react = [
        // the name of the generated asset file containing your JS bundle
    bundleAssetName: "index.android.bundle",

    // the entry file for bundle generation
    entryFile: "index.android.js",

    // whether to bundle JS and assets in debug mode
    bundleInDebug: false,

    // whether to bundle JS and assets in release mode
    bundleInRelease: true,

    // the root of your project, i.e. where "package.json" lives
    root: "../../",

    // where to put the JS bundle asset in debug mode
    jsBundleDirDebug: "$buildDir/intermediates/assets/debug",

    // …

我正在尝试使用RecyclerView和GridLayoutManager制作一个3列网格,我ItemDecoration用来制作列间距,现在问题是第三列中项目的宽度小于第一列和第二列中的项目!请参阅下面的屏幕截图.

如果我不添加自定义ItemDecoration到RecyclerView,一切都OK了.

这是我的代码:

MainActivity.java:

public class MainActivity extends AppCompatActivity {

    private RecyclerView mRecyclerView;
    private MyAdapter mAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
        mAdapter = new MyAdapter();
        mRecyclerView.setAdapter(mAdapter);

        GridLayoutManager gridLayoutManager = new GridLayoutManager(this, 3);
        mRecyclerView.setLayoutManager(gridLayoutManager);

        int horizontalSpacing = 20;
        int verticalSpacing = 10;
        SpacingDecoration decoration = new SpacingDecoration(horizontalSpacing, verticalSpacing, true);
        mRecyclerView.addItemDecoration(decoration);
    }


    private static class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

        private int[] mColors = new int[]{Color.RED, …

就在不久前,我在GitHub上四处寻找,我发现在一些strings.xml中的字符串值旁边有一些双引号,如下所示:

<string name="ClipMmi" msgid="6952821216480289285">"????"</string>

总之,我的意思是这个

"????"

有关完整示例,请单击此处.

我不知道用于什么？因为如果我删除字符串旁边的""(例如"来电显示"改为来电显示),输出就不会再改变了,"来电显示"和来电显示都将打印来电显示为输出.

那么引文在这里有意义吗？
